Currently the company I work is running a campaign to offer and implement Dynamics for Marketing. However, We have a frequent question that is always a huge headache to close the Deal. Dynamics for Marketing does not allow Marketing Email Attachments. There are a few workarounds available such as SharePoint and Azure Blob, but it's not user friendly. The Idea would allow marketing user to attach PDF or any other file while designing the Marketing Email. So, once the customer open and read the email is possible to select a button to download the PDF or document or send as Attachment whatever. This is a very important feature I have seen many Dynamics for Marketing requesting in many forums threads.
